WRENCH.

Application filed ()ctober 13, 1922. Serial No. 594,259.

To all whom it may concern-.-

Be it known that I, Fomin BAIN, a citizen of the United States, residing at La Grange, in the county of Cook and State of Illinois,

have invented certain new and useful Improvements in renches, of which the following is a specification.

The invention relates to wrenches.

. )ne of the objects is to provide a plurality of pivoted-togetherv wrenches so arranged that any. one of the group of wrenches maybe extended for use and means for positively holding the extended wrench in rigid operative position with respect to those of the group not extended.

A further object is to provide a group of wrenches, any two of which may be placed in aligning operative position and positively held so that the two wrenches may be selectivelyused while the otheris utilized as a handle.

Another object is to provide a set of wrenches: arranged side by side in a group and pivoted together at one end, to occupy relatively small space and having means to rigidly hold an extended wrench which may be moved into substantially axial position with respect to those remainingnested in the group. 7

Otheradvantages and more specific objects of the invention will hereinafter ap-.

pear to persons skilled in the art, from a 4% consideration of the following description when taken in conjunction vwith'the draw ings, wherein Fig. '1 is a side elevation, showing parts in section, of a group of wrenches with one wrench extended for use.

Fig. 2 is a side elevation of a group of wrenches contracted into compact form.

Fig. 3 is a plan View of thesame.

Fig. 4 is auside elevation of a single wrench of a group.

Fig. 5 shows a plurality of wrenches grouped together, any two of which form an S-wrench when in substantially axial alignment, and showing how other wrenches of the group may be made to occupy an intermediate position, when necessary.

In all of the views the same reference characters are used to indicate corresponding parts.

Each wrench A. is provided with a rounded end 10 having a concentric perforation 11 and shoulders 12 and 18, one on each side aboutthe pivot pin.

memberslo and 16, which perforations are in register with the perforations 11 in the wrenches. The wrenches are pivoted together and to the clip by the pin 17. The

wrenches and the clip are rotatably movable about the pin. When the wrenches are nested 'or contracted the yoke, 14:, may occupy the position shown in Fig. 3 in which position it does not engage any of the shoulders 1213 of the wrenches. Assume, for example, that the wrench A is required to tighten a nut. This wrench may be raised from the group on the right and rotated to the left, this operationwillrotate the clip lt'until its yoke let is brought between shoulder 13 of wrench Av and shoulder 12 of all of the wrenches remaining in the group on the right side of the pivotal point. The wrenches A and A inclusive, may now be used as a handle for wrench A The yoke 1 1 now between shoulders 12 and 13, rigidly connects the extended wrench, in this case A with the others of the group and the strain from the'handle will be transmitted thru shoulders12'13 and yoke l l to wrench A In this example, strain isapplied to pull down on the handle comprising the group of wrenches, on the right side. of the pivot. Now, assume that it is desirable to unscrew a nutor bolt with wrenchA by pushing up on the handle. Wrench A is closed and again extended from the opposite direction, that is to say, wrench A is caused to 7 make one complete revolution This will move the yoke 14 to the opposite sideof the pin between shoulder 12 of wrench A and shoulders 7.13 of the group, whereupon the wrench A is thus rigidly connected to the group when pressure is applied to raise the group handle and unscrew a nut or bolt with wrench A Instead of doing this, however,

the tool may be reversed by turning it bottom side up and thus effect the same rigid connection when direction of rotation is to be changed.

In Fig; 5 the wrenches are shown with one straight side to provide a smoother handle and when one wrench is extended from the group, the aligning wrenches resemble the well-known Swrench.

In Fig. 5 the aligning wrenches A and A may both be available for use, by employing claim as new and desire to extended.

the other one asthe' handle, while the remaining wrenches of the group may be moved to an intermediate idle position about the pivot.

In many situations relatively short wrenches, joined together as herein pointed out, are adaptable for use where a longer wrench would not serve so well, if at all, and

to meet other contingencies the usual advantages of a longer wrench is immediately available.

The wrenches could be made to serve their purpose very satisfactorily by omitting one shoulder from each of the wrenches and by arrangedto abut both shoulders and to-be included therebetween when one wrench is I 2L Ina foldable tool a plurality of parallel wrenches, each, having an operative head and a shank, the latter perforated near its end and provid ng a pair of transversely extending abrupt shoulders near said per foration; a U shaped clip rotatable about said perforations to alternately engage the -"shoulders on each side of the perforations and a pin passing thru the perforations of all of the wrenches and thru the clip.

3. In a foldable toola plurality of parallel wrenches, each having'an operative head and a shank, the latter perforated near its end andby reduction in size about said perforation providing a pair'of transversely aligning abrupt shoulders near said perforation; a U-shaped clip rotatable about said perforations to alternately engage the shoulders on each side of the perforationsand to engage shoulders on opposite sides of the longitudinal axes of two aligning wrenches when one wrench is extended.

4. In a foldable tool, a plurality of like stacked wrenches, each wrench having a perforation thru the end of its shank and having an abrupt shoulder on opposite sides of the perforation, provided by reduction of the section of the shank, said perforations and shoulders of all of the wrenches in a transverse plane passing thru said shank; a U-shaped clip having holes aligning with the holes of the wrenches encompassing the ends thereof and rotatable thereabout to bring the yoke of the clip alternatively into contact with the two sets of shoulders and a pin passing thru the clip and thru all of the wrenches to pivot them together.

5. A foldable tool comprising a plurality of wrenches having reduced perforated rounded ends in which the perforations register and each wrench having a transversely extending shoulder on each side near the perforation provided by the reduced end; a U-shape clip overlying the perforated ends, the yoke of which engages all of the shoulders on one side and a pinpassing'thru the clip and through all of the perforations of the wrenches.

6. A foldable tool comprising a plurality of wrenches having reduced perforated rounded ends in which the perforations register, and each wrench having an abrupt shoulder on each side near the perforation provided by said reduced end; a U-shape clip overlying the perforated ends, the yoke of which may engage all of the shoulders on one side and rotatable to engage the shoulders of the opposite side; and a pin, passing thru the clip and through all of the wrenches, upon which said clip and wrenches are rotatable.

7. A tool comprising a plurality of wrenches, each wrench having a reduced, rounded perforated end and a shoulder on each side of the reduced part at its juncture with the larger shank of the wrench; a U- shape clip overlying the reduced ends of the wrenches, and rotatable about said ends; a pin passing thru the side walls of the clip and thru the wrenches, the yoke of the clip lying between the shoulders of two wrenches when one wrench isextended.

In testimony whereof I hereunto subscribed my name.
